Suspension & Steering Shopping List

Fancy!!!

I might have to look at those for my Challenger when I get it going again. Not a fan of the heims on the Hotchkis arms I have now on it.

The Gen I SPC’s come without the ball joint, the BAC version has Delrin bushings though



They redesigned version of the QA1 LCA’s have a bumpstop built in. The first generation of them did not (mine don’t). It’s good that they have a bumpstop, but, it got rid of one of the biggest benefits of the tubular LCA’s which is that they give back about 1” of suspension travel. Which is very nice for lowered cars. The QA1 update basically returned the travel to stock because the bump stop and mount they use is so tall. I think it could be modified though. I put my bumpstops onto the frame horn for the original bump stop.

You’ll still need an upper bumpstop for the SPC arms. You can use the stop bumpstop, but you may need to drill a new hole in the frame extension so hit contacts the arm.

Got it. I haven't had the font wheels off since i rebuilt the brakes two years ago when i first got it on the road after it's 20 year hiatus. That said, i'm not terribly familiar with all the goings on under there currently. I had to go out and look at the lower control arm with a flashlight last night because i was looking at the QA1 unit and couldnt understand how the ball joint connected, lol. Not to worry though, I'm sure i will become intimately familiar with both the front and rear suspension soon enough.

Is there a recommended upper bump stop? And if the QA1 bump stop is going to hinder needed travel, I will need to get that sorted out as well. I was actually somewhat on the fence about just doing the reinforcing plates on my stock LCA's but I also like the idea of keeping them original in case my car ever has to go back to stock. I'm sure it wouldn't be terribly hard to find replacement LCA's with the 67 sway bar mount, but knowing i have the unmolested originals gives me the warm and fuzzies. My research (basically just your postings lol) has also led me to believe that the Hotchkis 67 sway bar will work with the QA1 LCA's with minimal fuss, modifying end links doesn't seem like the end of the world to me.
